SIDE-ILAY LINER FOR LOCOMOTIVE-TRUCKS.

Specification of Letters Patent.

Patented Sept. 13, 1910.

Application filed May 7, 1910. Serial No. 559,985.

To all whom it may concern:

Be it known that we, IVILLIAM HENRY Tnons and HORACE human DUMMERT, ofthe town of Carleton Place, in the county of Lanai-k, Province ofOntario, Dominion of Canada, subjects of the King of Great Britain, haveinvented certain new and useful Improvements in Side-Play Liners forLocomotive-Trucks; and we do hereby declare that the following is afull, clear, and exact description of the same.

The invention relates to improvements in side play liners for locomotivetrucks, as described in the present specification and illustrated in theaccompanying drawings that form part of the same.

The invention consists essentially in the novel construction andarrangement of parts whereby the liner may be placed in position withoutremoving the wheel from the axle by rigidly supporting said liner withlaterally arranged arms securely bolted to said wheel.

The objects of the invention are to obviate the necessity of removingthe wheel to replace liners, to devise a liner of simple and durableconstruction and generally to effect economy in the maintenance oflocomotive trucks.

In the drawings, Figure 1 is an inside elevation of a locomotive wheeland journal box showing the axle in cross section and the position ofthe liner arms. Fig. 2 is a vertical mid-section on the line A-B inFig. 1. Fig. 3 is a plan view of the liner arms combined with alongitudinal sectional view of said arms and cross sectional View of theliner. Fig. 1 is a perspective detail of the liner and arms. Fig. 5 is across sectional View of the arms on the line AB in Fig. 4, showing aportion of the Wheel in section. Fig. 6 is a plan View of a modificationof the liner arms.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the rim of the Wheel, 2 is the web ofthe wheel securely attached to said rim by the bolts 3.

4 is the axle arranged in the center of the web of the wheel ascustomary.

5 is the journal box supported by the brackets 6 and slidably arrangedtherein, said brackets being ri 'idly secured to the truck beam 7. Theax e 4: extends through said journal box 5 into the center of the web 2.

8 is a bushing encircling the axle within the hub of the wheel.

9 is a bushing encircling the axle within the journal box casing.

10 is a side play liner, split centrally and in the form of a washerencircling the axle 1, and abutting the ournal box 5.

11 and 12 are arms preferably longitudinally tongued and grooved intheir inner sides 13 and 14 respectively and having the central expandedportion 15 forming the axle orifice 16, said central portion 15 beingrigidly secured to the halves of the liner 10 by welding or othersuitable process.

17 are bolt holes at the ends of the arms 11 and 12.

In separating the arms 11 and 12, each arm carries a half of the liner10, said arms being brought together and in the central portion thereofencircling the axle 4, thus the liner 10 is between the journal boxcasing and said arms. The arms at the ends thereof are securely boltedto the web 2 and the rim 1, preferably by some of the same bolts 3 asare used for securing said rim and web together, therefore, the linerand its supporting arms are, to all intents and purposes a fixed part ofthe wheel structure and no screws or bolts are in the central portionthereof, with the result that the continuous side play cannot have anyeffect on said liner, other than the ordinary wear and tear and as itgradually becomes worn so much so that it must be replaced, the arms canbe removed without ditliculty, thus taking the liner away andsubstituting new parts. All this can be done without removing the wheelfrom the axle, as it is only necessary to remove those particular bolts3 that secure said arms to the wheel.

In Fig. 6, a modification of the arrangement of arms is shown and theonly difference being that from a central body 18, which is split andencircles the axle, the arms 19 extend outwardly and radially and arebolted to the wheel in the same manner, of course, it is obvious thatany number of arms may be used.

\Vhat we claim as our invention is 1. In side play liners for locomotivetrucks, the combination with the wheel, axle and the journal box throughwhich said axle extends, of a plate of metal split centrally and havinga central axle orifice there through and arms rigid With said plate ofmetal and extending laterally therefrom and securely bolted to saidWheel.

2. In side play liners for locomotive trucks, the combination With theWheel, axle and the journal box through Which said axle extends, of aplate of metal split centrally and having the axle orifice therethrough,and arms rigidly secured to the halves of said plate of metalrespectively and formed in the central portion into a correspond ingaxle orifice and securely bolted to said Wheels.

3. In side play liners for locomotive trucks, the combination With theWheel, axle and the journal box through Which said, axle extends, of ametal disk split centrally having its halves form an axle orificetherethrough and a plurality of arms extending from a central split bodyportion, the latter being securely Welded to the halves of said disk andthe former being rigidly secured to said Wheel adjacent to the rimthereof.

4. In side play liners for locomotive trucks, the combination With theWheel, axle and the journal box through Which said axle extends, of ametal disk split centrally and having its halves form an axle orifice,and a pair of arms centrally forming a corresponding axle orifice andrigidly secured to said disk halves respectively and having a tongue andgroove formation respectively on their inner sides and at their outerend bolt holes and bolts rigidly securing said arms to said Wheeladjacent to the rim thereof.
